DUSTLESS ASH-SIETER.

M l Specoationof Letters Patent.

To all 'whom t may concern:

Be it known that I, JOHN E. PERTL a subject of the Emperor of Austria, residing at Palms, in the county of Los Angeles and State of California, have invented new and useful Improvements in Dustless Ash-Sifters, of which the following is a specication. My object is to make a dustless ash sifter and` `consists in the `novel features herein shown, described and claimed. Figure 1 is a top plan view of a dustless ash sifter embodying the principles of my invention, parts being broken away.

Fig. 2 is a cross-section on the lines 2`2 of Eigs. 1 and 3.

ig. 3 is a vertical longitudinal section on the lines 3-3 of Figs. 1 and 2. Fig. 4 is an `enlargedA fragmentary sectional detail on the line 4`4 of Fig. 2.

Fig. 5 is an enlarged fragmentary sectional detail on the line 5-5 of Fig. 1. y Fig. 6 is an enlarged detail of a piece of the sprinkler pipe.

The main body of the ash sifter is a rectangular box comprising vertical walls l, 2,

the walls 1, 2, 3 and 4` and fills substantially one-half of the space, the other halfof the space being occupied by an opening 7. A slide 8 is insert-ed through the wall 4 above the bottom 6 to close the opening 7. An inclined baffle plate 9 is secured to the wall 4 some distance from the bottom andextends inwardly and downwardly toward the opening 7. A bracket 10 extends downwardly from the center of the slide 8, and retractile coil springs 11 and 12 are connected to the bracket 10 and extend diagonally to the rear corners and are attached to the rear corner prevent the slide from binding on the sides. An inclined chute 13 leads through the upper so that the door and so that the door cinders pass down the chute, gravity open when .inits horizontal position upper edges of the pan near their spout 17. Bearing plates 2O and 21`are fixed' to the inner faces of the walls 2 and 4 and said plateshave slotted bearings 22 toreceive the trunn-ions 18 and 19 so as to pi-votally mount the sifter pan. The sifterpan 16 has a screen. -bottom 23. The sifter pan 16 is held by resting upon the trunnions 18 and 19in the plates 2O and 2l and-the top of the spout 17 bearing upwardly against the top of the chute 13.

rear ends, that is, near the- A opper 24 extends upwardly from the walls 1, 2, 3 and 4, a cover is connected to one side of the hopper by hinges 26, and a folding link 27 connects the cover 25to the hopper, so that when the `cover is raised to a vertical positionand overbalanced slightly the link 27 will support thecover.`

A crank shaft 28 ismounted in a bearing 29 carried by a bracket 30 and the bracket 30 `is secured to the upper part of the `wall 3. A crankwheel `31 is 'xed upon the outer end of theshaft 28 and a crank handle 32 is fixed to the crank wheel for manuallyoperating the wheel. The whee 31 serves as a fly wheel A cam 33 is fixed upon the inner end of la cam shaft, said cani shaft extending through a bearing 34 and said bearing 34 extending through the wall 3, and gears 36 and 37 connect the crank shaft 28 to the cam shaft, so that when the handle 32 is manually operated the cam 33 rotates, and the cam face 38 in the pan, and the dust and ashes will pass downwardly through the screen 23 into the chamber 39 of the box. i A handle 40 extends upwardly from the sifter pan 16 so that when the ashes have been sifted out of the cinders the handle 40 is manually operated to raise the free end of the si er pan, and tilt the pan upon the trunnions 18 and 19 to discharge the cinders through the spout 17 to the chute 13. A pail or coal-hod may be placed under the chute to receive the cinders.

A check-valve casting or block 41 is placed against the inner face of the wall 3 and the nipple 42 of a stop-cock 43 is screwed through the wall 3 into the block 41. The

Y water pipe 44 'is attached to thestop-Vc'ock ybracket 57 and pivot pin 43. A horizontal passage 45 leads from the nipple 42 to a vertical -passage 46, there being a valve seat 47 at theV upper end of the vertical Vpassage 46. A passage '48 leads vfrom above the valve'seat 47 and the sprinkler pipe 49'lea-ds from this passage 48. The sprinkler pipe 49 extends around three sides of the box and discharging Y horizontally inwardly. The valve member 51y tsuponthe seatV 47 and has a stem 52 extending downwardly through the block 41. A spring casing 53 is screwed into the block 41 from the top and a spring 54 inthe easing 53 engages the valve 51 to `hold it yieldingly' upon the seat 47, the tension of the spring being suiicient to hold the water pressure coming through the stop-cock 43. Y Thertip 55 ofthe stem 52 extends some distance below the block 41.' A lever 56 is kpivotally mounted inv a horizontal Yposition against the innerffaceof the wall 3 upon a 58. The pivot pin I i. 58 is substantially at the centeriofVV the lever 56. YArroller 59 is carried Vby 'one end of the lever- 56 in position to be engaged by the cam YJface 38, and the opposite end 60 of the lever is in positionto engage Vthe tip'55` of the valve stem,`so that when the stop-cock 43 is open and the siftingoperation is being carried on the cam Jface 38 will engage the roller 59f'a't eachi revolution of the cam and press the roller 59 downwardly, thereby pressing the'end 60 of the lever upwardly to unseat the valve- 51 and allow water to shoot through the sprinkler pipe 49 and through Copies. of this patent may 'be obtained for ve cents each, by addressing the has slits forming nozzles 50 rvalve in the water pipe,

thel nozzles 50 so as to sprinkle the interior of the chamber 39 and settle the ashes and dust. The wet ashes and dust will fall upon the slide 8 and the baiiie 9 until a sufficient quantity has been accumulated and then the handle 61 of the slide 8 is grasped to pull the slide against the tensions oi the springs 11 and 12 to uncover the opening 7 and allow the wet ashes and dust to i'all through the opening.

Various changes may be made in the details of construction without departing Jtrom the spirit of my invention as claimed.
